SPECIFICATION forming part of Letters Patent No. 744,500, dated November 17, 1903. Application filed July 8 1903. Serial No. 164,716. (No model.)

To all whom it may concern.-

Be it known that I, CARL WASHBURN DECKER, of Charles City, inthe county of Floyd and State of Iowa, have invented a new and useful Improvement in Windmill-Pump alone, the same being intended to provide a pump which can be made at "comparatively small cost and great simplicity of parts.

' A further object is to so constructthe parts as to make it impossible for both hand=lever and windmill-rod to be coupled to the pistonrod of the pump at one and the same time.

My invention consists in the novel construction and arrangement ofjparts hereinafter described, and pointed out in the claims. Figure 1 is a side elevation of the coupling. Fig. 2 is an enlarged cross-section on line 2 2 of Fig. 1. Fig. 3 is an enlarged cross-section on line 3 3 of Fig. 1. Fig. 4 is "a detail of the locking-yoke. Fig. 5 is a side view of the lower end of the shifting-bar. Fig. 6 is a section taken on the line 6 6 of Fig. 5, showing also a portion of the pump-rodand the wind-- mill-locking device. Fig. 7 is an edge and side view of the connection for the windmillrod, and Fig. 8 is a detail of the under side of the upper end of the hand-lever.

' In Fig. 1 of the drawings, 1 represents the pump-head. 2 is the rocker-arm support, 3

the hand-lever, and 4 the piston-rod, of an ordinary windmill-pump.

A indicates a spring the object of which 40 is to support the weight of the pump-rod 4 and the water'in the pump, said rod being supported in its lower position upon said spring by means'of "a ring B, riveted to the pump-rod a short distance below the point of connection with the hand-lever.

C is a vertical shifting-bar arranged beside the pump-piston rod and having in its length a bend at cand another at 0'. This shiftingbar has also at its lower end an enlarged cyl-indrical-shaped cross-piece C Fig. 5, which is adapted to be retained inhand carried by the upper end of thehand-lever.

. G is asliding sleeve-coupling which is attached to the lower end of the windmill-rod and is adapted also to receive the upper end of the piston-rod of the pump. This sleevecouplingG has at its lower end' on opposite.

sides holes h, adapted to receive pins D It of a two-part yoke D and-E, ('see Fig. 4,)

which embraces the lower end of the sleeve G. This yoke slides horizontally and serves, as hereinafter described, .to lock together or unlock the piston-rod and the windmill-rod. The pins D E slide in holes in the lower end of sleeve G, and the pin D, when the yoke is slid to the left in Fig. 1, enters also a notch 'n in the piston-rod 4. In the yoke D E there is on one side a larger space between the pins ID E and the side of the yoke than there is on the other, and in operation the shiftingbar C plays freely in this larger opening with in the yoke and beside the sleeve G. The

horizontal sliding of the yoke D E to lock or unlock the piston-rod and windmill is efiected by a spring F in one direction and by the curved portion 0 of the shifting-bar C in the other direction. This shifting-bar is oper ated from below by the hand-lever, as will be presently described.

The piston-rod 4 extends through a guide I, formed in the standards I rising from the pump-head, and saidpiston-rod is notched at n (see Fig. 6) at a point below the guide I" to provide a means of coupling to the handlever. The upper notchn is at a point at such a distance above this lower notch n that p when piston-rod '4 is carried to its highest extremity of stroke the upper notch is opposite the point reached by yoke DE when carried to the highest extremity of stroke by the windmill, so that when piston-rod 4 having been carried to its highest point of stroke by the The couplingot' the hand-lever to the piston-rod is effected through the shifting-bar C, as seen in Figs. 5 and 6. The lower end of this bar carries in its cylindrical head a dog J, acted upon by a spring I, which is itself carried within a hollow screw H, the latter being screwed into the rear side of the cylindricalshaped cross-head at the lower end of bar 0. The front side of this cylindrical cross-head is cut away or grooved vertically to receive the edge of the piston-rod 4, and when the notch 71' of the piston-rod is opposite the dog J the spring I forces the dog into the notch of the piston-rod and couples the piston-rod and shiftingbar C, which latter is by its cylindrical cross-head connected to the handlever 3. This hand-lever is at its upper end so constructed as to carry the lower end of bar 0 intoa position similar to that occupied by the pin used in ordinary pumps. One side of the lever (see Fig. 8) has an openinglarge enough to allow the passage of the bar 0 when the lower part of bar 0 is put in place in its bearings in the hand-lever 3. This opening just mentioned being on the lower front side of the bearing in lever 3 when bar 0 is in proper position in the pump makes the position of O in its bearings secure.

In the upper ends of standards I are formed hook-shaped recesses or seats 1 into which the cross-head of bar 0 and the upper end of hand-lever 3 rise and move away from the piston-rod when the hand lever is thrown down.

It will be seen from the foregoing description that when, after the hand-1e ver has been used in pumping, its free end is dropped to nearly its lowest point the upper end of the hand-lever carries the lower end of bar 0 back out of connection with lower notch in piston-rod 4. As the lower end of hand-lever 3 is moved still farther to the lowest extremity of its stroke the lower end of bar 0 is carried to a point far enough back in seat I so that the upper portion of bar C is forced forward by the pressure of spring F upon yoke D E, allowing pin D to engage upper notch 91 in piston-rod 4:, ashas been described. In this case pin D must engage upper notch n in rod 4 as soon as the windmill causes sleeve G to move a su fficient distance upward. Now if the windmill-rod is in connection with piston-rod 4 by means of locking-yoke D E and sleeve G and it is desired to disconnect windmill-rod and connect hand-lever to piston-rod 4, if hand-lever3 is lifted by the hand the lower end of 0 moves toward piston-rod 4, and as the bar 0 bears upon guide I at X the upper end of O is forced backward away from piston-rod 4, forcing yoke D E back and withdrawing pin D from notch 91. in the pistonrod. As lever 3 is lifted still farther in this same direction by the hand the lower end of bar 0 is brought in contact with back edge of rod 4. If the lower part of bar 0 is now opposite lower notch in 4, dog J will be forced into this notch by spring I. If, on the other hand, this notch is not opposite dog J, it

must be at some point below, and as bar 0 is carried by motion of lever 3 still farther downward dog J must finally reach a point opposite this notch and engage it, as pistonrod 4 cannot drop too far, being supported by ring B, resting upon spring A. It will thus be seen that it is impossible for the hand-lever and windmill-rod to be in connection with the piston-rod of the pump at the same time and that the coupling of the handlever to, the piston -rod and uncoupling of windmill-rod from the same, or vice versa, is accomplished by making use of the last portion of the upper end of stroke of the upper end of hand-lever only, making this device very convenient.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-- l. A windmill-pump coupling, comprising a stationary guide mounted upon the pumphead, a piston-rod having a notch above and another notch below said guide, a clutchcoupling for the Windmill-rod and the upper notch of the piston-rod, a clutch-coupling for the hand-lever and the lower notch of the piston-rod and a vertical shifting-bar connecting these two clutch-couplings and having a tilting hearing at an intermediate point against the stationary guide substantially as described.
